“I think ZERO Sievert is a decent game at its core, and the idea behind it is genuinely interesting. A full solo extraction shooter is a rare thing on the market, and that alone already makes this project stand out. If…”
“Addictive gameplay but banch of technical issues [h3]pros:[/h3] + stalker like setting + extraction shooter core gameplay + weapon and ammuntion assortment [h3]cons:[/h3] - [b]memory leak issue when going into pause…”
“Unfinished game that is rushing to get a sequel out of it, It was fun while it lasted.”

“Stress free extraction shooter very simple control and learning curve. very enjoyable”
“Don't let the pixel art fool you; this game is as tough as nails and a hell of a lot of fun! The development team is crazy active and they are still working on meaningful updates even now, over a year and a half after…”
“If you like tarkov with stalker elements this game is for you. The 2D art style is also quite nice. At first I thought it was goofy but I came to like it. The story is actually surprisingly good and thought out so that…”

“Good game, Solid mechanics, Hard Bosses. Truly the best 8-bit style game I have played in years. Can't wait for Zero Sievert 2, Just hope they continue to update the original with new content as well.”

“The developers listen to their fans, which is a great plus. Though the delivery speed and quality always has been subpar. The game has had immersion killing bugs for most of its development but I can forgive that given…”
“This game is NOT being abandoned and is NOT in a complete state. The devs, if anyone downvoting this game, STILL HAVE huge updates planned and have been teasing and hinting at it releasing soon for this game, while an…”

“Zero Sievert is a game that reflects the replay ability of the S.T.A.L.K.E.R series and the thrill of an extraction shooter like Escape from Tarkov. But this game is nothing like them as everything you do and the…”
“This game shares DNA with extraction shooters and rogue-likes, with mild base building and leveling mechanics. Procedural generation keeps me coming back to see what else I can discover.”
“bit of a learning curve but very addicting and replayable”

“Game still feels very much in early access. Don't buy!”
“Dev says its a full release, but it's still very early access and they started making a sequel, instead of further developing their game. Avoid.”
“fake full release. still early access”

“The game doesn't hold your hand. There are times when you feel as if your death is justified and sometimes when you call 100% BS. But it's honestly fun. Spawn in, loot loot loot, gtfo. There is a slight sense of horror…”
“Basically top down stalker. Not the best at introducing players on how to play (much like stalker) but still absolutely worth the cost. I haven't beaten it as of writing this review but i don't anticipate regretting my…”

“I'm writing this review because some of the recent negative reviews are plain sdubid and put the game in "mixed" and it's totally unfair. I hate writing overly long reviews but I think this might be useful to those thinking of buying and being unsure cause of said negative…”

I love punishing games but my reaction times have greatly diminished over the years. I constantly die to the most mundane things in this game because I did not notice them…”
